Definitions

  • FIG. 8 is an exploded sectional view of the shock module of FIG. 7, illustrating a preferred configuration of the end cap and O-ring assembly;
  • FIG. 12 is a sectional view of the lower pylon, end fitting, and guide pin assembly of the shock module of FIG. 9A;
  • FIG. 22 is a side view illustrating an alternative attachment of a shock module of the invention to a prosthetic foot.
  • Shock module 22 includes telescoping hollow cylindrical pylons 26 and 28 , shaped and adapted for smooth relative motion. Pylons 26 and 28 are preferably slidingly and rotationally interengaged with each other while retaining their operative horizontal alignment with each other through a relatively close fit between the inside dimensions of outer pylon 26 and the outside dimensions of inner pylon 28 .
  • Inner pylon 28 is adapted to be attached to a stump socket 44 , as described later herein.
  • Outer pylon 26 preferably has a cylindrical outer surface to facilitate the attachment of various types of prosthetic feet using conventional prosthetic couplers.
  • the lower end of pylon 26 may be attached to a prosthetic foot having a horizontal attachment section, such as the prosthetic foot 24 in FIG. 1, or to a prosthetic foot having a vertical attachment section. Both types of attachments are well known in the prosthetic foot art.
  • a torque-resisting cuff 34 provides torsion-resistance to the prosthesis and also keeps dirt and other debris from getting between pylons 26 and 28 and affecting their relative motion.
  • the cuff 34 may be configured to provide some additional impact resistance.
  • the cuff 34 is proximally attached to inner pylon 28 and distally attached to outer pylon 26 . Preferably, both of these attachments are near the proximal ends of said pylons and are made via ring clamps 50 which provide air-tight seals.
  • FIGS. 1A and 2 illustrate one example of an attachment construction for attaching the proximal end of the shock module 22 to a stump-supporting socket.
  • a male pyramid fitting 36 is fixed to the proximal end of inner pylon 28 and is adapted to be coupled to female pyramid fitting 46 .
  • This assembly allows the shock module 22 to be proximally attached to a broad selection of prosthetic sockets (for example, in FIG. 1A, to a stump socket 44 via an alignment cup 48 ) or other intermediate prosthetic devises, such as a prosthetic knee.
